Hi, I'm currently trying to upgrade my xwiki installations from 5.4.4 to 8.0 (or even later, byt currentrly struggling with 8.0). Current (5.4.4) installation have a few modifications made in base XWiki documents. We have provided the installation with our library to authenticate users from external application along with few service components etc. And now I'm loooking for best way to migrate to later(lates) version. With it I have a few issues. - Distribution Wizard is not working properly when run on server (tomcat) with our extensions and modifications provided. It displays information about component not being compatibile. There is allways a way to run a clean xwiki and migrate with Distribution Wizard but for now I would like to avoid it. - Another issue using Distribution Wizard is that not all of installation environments have access to extension repositories. - Another thing is that one of installations have huge ammount of attachments (over 100 GB) so exporting old installation and importing over new installation is not possible. Does anyone have any tips regarding XWiki migration? I will be greateful for any help, even for som words of encouragement ;) Karol -- View this message in context: http://xwiki.475771.n2.nabble.com/XWiki-migration-tp7601313.html Sent from the XWiki- Users mailing list archive at Nabble.com.
